Peppy Five is a wooden educational toy. This colourful five stem stacker aids children to learn counting and to understand number concepts. Lacware wooden toy made by Channapatna artisans. This toy is just one of the manifestations of the traditional Lacware craft from India. Lacware craft involves an eco-friendly manufacturing process.

A computer graphic with adjustable paramaters, said to illustrate the concept of the harmonics of a weighted string. The graphic display, itself, is poorly documented - we don't know what we are seeing, but we know that it can't be the chain, itself, as the movement is generally circular, not linear and largely screen filling, even for small perturbations. The pictures are, however, pretty, and this is a mildly enjoyable toy. Without further clarification, though, I can not, in good conscience, do as others have done and classify this as "science" or "physics" because no real learning is taking place.
